Abstract

To circumvent the limitations of polyethylene glycol (PEG) modified carriers, a photo-triggerable liposome was prepared which was modified by cholesterol derivatives via a cleavable vinyl ether linkage so that the PEGylated coating can be efficiently removed by a photoactivated fullerene. After the photocleavage of the PEG moiety, the intracellular uptake of the photo-triggerable liposome improved.
